Just finished about an hour ago, and I was real thorough in the prep, and though the stuff is hard to keep from sticking to everything, managed to get it on all areas of window without a mess on the canvas or car. It does seem to be the ticket, and the nature of this stuff being somewhat flexible, makes it removable if another repair is necessary down the line. I will let everyone know if my repair is successful down the line. Thanks for the great post on this repair. STEVE T
